Gunsmith description

The 17.2" Bull Barrel returns in Call of Duty: Mobile, where it is also exclusively available to the HDR sniper rifle.

Upon equipping, it considerably increases vertical recoil control by 40%, as well as enabling the HDR to recenter back to initial spot while aiming down sight.

On the other hand, the attachment blocks access to all Muzzle attachments, and reduces ADS speed, movement speed and damage range by 10.0%, 4.0% and 12.0% respectively.
